[markuspi]

Description of the bug

Using the new overloads_only: true option introduced in #286 does not work for __init__ functions when merge_init_into_class: true is set.

To Reproduce

Options:

overloads_only: true
show_overloads: true
separate_signature: true
merge_init_into_class: true

Python:

from typing import overload

class Class:
    @overload
    def __init__(self, a: int, b: str): ...
    @overload
    def __init__(self, a: str, b: int): ...
    def __init__(self, a: int | str, b: int | str):
        """Some docstring."""

MRE
